To all whom it may concern:

Be it known that I, FRANK B. DAVIDSON, a citizen of the United States, and a resident of Marseilles, in the county of Lasalle and State of Illinois, have invented certain new and useful Im rovements in Containers; and eclare that the following is a reference being had to the accompanying drawin s, and to the letters of reference marke thereon, which form a part of this specification.

This invention relates to a novel paper box or container made from a single sheet of sti or heavypaper-board, straw-board or like sheet material and designed more especially to be used in the place of a wooden packing box for containing a number of packages, :filled cartons or the like.

Theinvention consists in the matters hereinafter set forth and more particularly point- Fig. 7 is a perspective view of a box of different dimensions, showing a slightly different manner of closing the top thereof. Fi 8 is a vertical longitudinal. section throu the top portion of said box shown in ig. 7. Fig. 9 is a vertical section on line 9-9 of Fig. 8. Fig. 10 is a lan view of a blank of slightly modified orm.- Fig. 11 is a plan viewof the top of a box made from said blank shown in Fig. 10. Fig. 12 is afragmentary plan view showing a modiiied form of the interlocking notch and tongue on the opposite iiaps of the box.

Said container is made from an elongated,-

single piece blank, shown in Fig. 2, which is bent into tubular form along the transverse score-lines a a1 a7 a3 and-provided at one of its ends with a short fla which is secured to the en margin of the opposite end of the blank by paste or other means. The four sections of the blank formed by said score-lines constitute the side Walls A A1 A2 A3 of the box and said sections iiaps A5 and A7.

Fig. 3 is a eror extensionA a4A are lprovided at their end margins with iiapsA* A5 e A7, separted from the said sections by score-lines a5 a. a7 a8 and from each other by slits perpendicular to the said score-lines.

In forming the container from the blank described the blank is bent along the scorelines into tubular form and the end iiap a4 secured to the op osite end of the blank. The marginal flaps A4 A5 A5 A7 at both sides of the blank are bent or turned inwardly with their ends overlap ing each other as clearly shown in Fig. 3. rEhese inturned end or top and bottom ,flaps form the top and bottom walls of the box. In Fi s. 3 to 6, inclusive, is shown the manner 0I forming the top wall or cover of the box, it being understood that the opposite or bottom wall is formed in an iden-A tical manner. As shown in Fig. -3 the a s A5 and A7 on the top mar ins of oppositesi e Walls A1 and Aa are first fgolded linward or toward each other and thereafter the iiaps A4 Y and Avare-folded toward each other over the As shown in Figs. 1 to 6, each of the two iiaps A5 and A7 extends less than half ofthe distance across the top of the box, leaving an opening between the inner or adjacent end margins of said lia s A5 and A7 which is closed by the two flaps 4 and A5. The two iiaps A4 and A8 meet at their inner margins of and al", respectively, and are adapted for interlocking engagement edge to edge with each other. As shown in sald Figs. 1 to 6, the flaps A4 and A6 are provided at their meeting edges, one with a tongue andv the other with a notch, and said tongue and notch are made generally of dove-tail shape so that when they are engaged with each other in edge to edge relation,'an interlocking connection will be formedl adapted to prevent the separation of said flaps from eachJ other. In the particular construction illustrated in said Figs. 1 to 6, the flap A4 is rovided on its margin with a tongue a w ich is formed by removing a ortion of the material at the corners of sai iiap along lines 0,12 a12 parallel with the margin a and along curved lines 0,13 a13 extending from the inner ends of said lines a.12 through the margin 0,9, and the flap A is provided on its inner margin am with a notch a14 and formed by cutting through the margin al into said flap along curved lines 0,15 (1.15 of the same shape as the curved lines L13 0.13, and alon alinea,16 ar. allel to the line al and of a ength equa to the length of the margin a of the iiap A5.

25 down upon and secured by paste, glue or other 45 f to which said outer fla s are attached in the In Figs. 3 to 6, inclusive, B indicates a reci tangular piece of sheet material, such as heavy paper or the like',I which covers the .s ace or a between the edges or margins of t e infol e fla s A5 and A7 and is interposed between the .a jacent surfaces of the external la s A* and A and the inner flaps A5 and aid sheet B overlaps and is pasted or otherwise A secured to the inner or adjacent margins of the flaps A5 and A7 and is likewise asted or otherwise secured to the inner suraces of the aps A4 and A". Said sheet extends across the top of the box the full distance between the outer margins of the flaps A4 and A5 but does not extend the full d1s,

tance between the outer margins of the Iiaps A5 and A7, or said sheet B may meet the top cover of the .box is formed b mar of the wallsA and A2 but may not reac to the walls Al and A3. As shown in said Figs. 3 to 6, inclusive, the top wall or irst folding down the aps A5 and A7 an securing the end portions of the sheet B to said iiaps A5 and A7 by paste, glue or other adhesive substance. T e laps A4 and A are then folded adhesive substance to sald sheet B and to the Ament with the notch 0.1.4.

' hold the iaps in their folded positions, and

such interlocking also serves to strengthen the end wall by resisting any tendency of the each other.

outer flaps -spreading a art under internal pressure exerted outwar y on the side walls s'ubsequenthandling o the box. The interlocking of said tongue and notch also insures the box being brought accurately into rectan ar form at the time of setting up or closing the box, because the tongue cannot be brou ht into en agement with the notch unless t e side wa s are at right angles to Such interlocking also serves, in the finished box, to aid ,the paste or glue in l holding the box in rectangular form, or from distortion by pressure coming on opposite corner edges thereof.

The adhesive substance used for securingl the outer ila s to the other arts constituting vthe end w may be applie between the entire inner surfaces of said outer fla s and the surfaces of the sheet B and flaps 5 and A7, or to a part only of said surfaces, the effect-'in any case being that the said outer flaps Vare secured to the inner flaps A5 and A7, and said .outer iiaps are held in thesame plane with each other, with the tongue and notch thereof in interlocking' engagement. B be omitted, the Asaid outer flaps will be secured by the paste or glue directly to the inner fla s A5 and A7, but whensaid sheet B is used t e same result will be obtained, because the said sheet will be secured in whole or in part at both sides thereof to the inner and outer flaps betweenwhich itis inter osed. The bottom wall of the box is forme in a manner in all respe'cts identicalwith the manl ner of forming the top wall or cover.

In Fig. 7 is shown a box of such dimensions that the iiaps A4 and A thereof meet along a line considerably longer than the meeting line ofthe iiaps A4 and A6 of the box shown 1n Figs. 1 to 6, inclusive. In FigsrS and 9 is shown the manner of forming the top wall or cover of said box shown in Fig. 7. As shown in said-Figs. 7, 8 and 9,.the box is constructed in the same manner as the box shown in Fig. 1 except that the sheet B is replaced 4.by a rectangular sheet C of heavy paper-board, straw-board or ylike material of lthe same length and breadth as the box. Said sheet C is interposed between the adj acentsurfaces of the inner iaps A5 and A7 and outer flaps A4 and A, as above described, and said sheet extends across the top of the box the full distance between the outer margins of the flaps A5 and A7 and A* andA and is secured by adhesivesubstance to the said inner and outer flaps.

Ifthe sheet In Figs. 10 and 11 is shown a form of coni struction in which the iiaps A4 and A6 are engaged or interlocked at their adjacent mar-l gms in a manner diiierent from that shown in Figs. 1 to 9, inclusive. As shown in said Fi s. 10 and 11, each of the flaps A4 is provi ed at its inner margin a.Q with a rectangular tongue-formed by cutting the side mar#4 gins of said iiaps along lines 0,17 a parallel with the margins a.9 and thence along lines per endicular thereto, extending through sail margin a". .Each of the flaps Ae is provided at its inner margin c1 with a rectangular notch formed by cutting through said margin along lines 0.15 (1,15 perpendicular thereto and thence along a line al arallel to said margin. The box shown in igs: 10 and 11 is closed by the useof an adhesive substance in the manner hereinbefore described, a sheet B being usually interposed between the adj acent surfaces of the iaps A5 and A7 and A4 and A5 as above described.

In the construction shownI in Figs.. 10 andL '11, the tongue and notch on the meeting.

edges of the outer flaps while they do not inter ock in a manner to hold the said flaps from spreading apart, serve the important purpose of. that the box body be rought accuratey into rect ar form when the aps are folded together in the act of forming the end wall or walls, because the tongue cannot be inserted in the notch in a manner to bring the side edges of the tongue into edge to edge engagement with the sides 5 of the notch, unless the side walls of the box be at'right angles to each other. Moreover, the interlocking of such tongue with the notch, in this form of the same, strengthens the box in a manner to resist a force ap lied 1o at one of its opposite vertical corner e ges, 1n a manner tending to distort or colla se the box. It is evident that in collapsing t e box by a force so ap lied, the meeting margins of the fla s A4 an A6 must shift or move endwise re atively to each other. The engagement of the said tongue with the notch of the associated flap manifestly acts to resist such relative movement of the outer flaps, and

thereby tends to strengthen the box. f

In Fig. 1-2 I have shown the opposite flaps A4 and A as provided with a tongue and notch which are made of dove-tail form, their lateral margins being straight and inclined, instead of curved, as illustratedin Figs. 1 to 7. The tongue and notch, when shaped as shown in said Fig. 12,A aHord the .same general result that is obtained by the construction shown in Figs. 1 to 7. The interlocking of said tongue and notch acting to hold the flaps from relative movement in the direction `of ythe meeting ed es thereof, and also preventing separation o the flaps by a move# ment away from each other to the extent re- 'quired to hold the flapstogether until the paste or glue used to close the end of the box as dried or hardened sufliciently to firmly secure the flaps in lace. 1

A container ma e in accordance with my invention is constructed of relatively stiff ed for use i ace of wooden packing boxes or cases for containing packages of light ma-I terials, such as cereals and the like. The end walls of the box, made as described, adord abox of great strength in pro `ortion to the amount of sheet material use in its construction, and the box, asa whole, may

be cheaply made and set up for use by un skilled labor.

In making up a ackage by the use of the container described), theila sA4 A5 `A6 A7 at ione end of the body will wardly and the end wall completed in the manner described. When one end wall has thus been formed the box will be turned to bring the completed wall downward and in contact with the floor or other flat sup orti-ng 1 The packages constituting t e con-v surface. tents of the container will then be inserted therein and the weight thereof, coming on the closed end wall, will hold the flaps constituting the latter in close contact with each other and under pressure until the paste or lue used for securing them together shall ave dried or hardened sufficiently to preor stronger paper or lstraw-board and adaptrstI be folded inalong the score-lines at opposite edges of thebox or container. The marginal flaps constituting the flanges are, in this instance, unfolded or in the same plane with the walls of the body or sections to which they are attachedn While I have shown in the accompanying drawings the outer flaps At and A8 as provided with a tongue and notch adapted for engagement with each other when the Y said flaps arebrought into the same plane or into edge to ed e relation, yet it is to be understood that t is feature may be applied as a means of joining opposite flaps arranged to meet each other as stated when the box isl constructed, in other respects, in a manner different from that illustrated and hereinbefore described.

While I prefer to emplo an adhesive substance for securin or hol ing in their folded positions the inter ocking fla l sin the manner set forth, yet many of the a vantages arising from my invention may be obtained in a box in which the said flaps are so held or secured in position by other fastening or securin means, and it is therefore to be understoo that my invention covers or includes a box in which the interlocked flaps are secured to a flat piece or pieces beneath them, or are otherwise secured in their foldedor interlocked position, either by an adhesive substance or other securing means.

I claim vas my invention 1. A box of sheet material having on opposite side Walls thereof flaps adapted to be folded inwardly and to meet each other edge to edge when brought into the same plane with each other, said flaps bein provided one with a notchand the other wit a ton e; said ton e being adapted to enter an fit Within .tl

site side walls thereof flaps adapted to be folded inwardly and to` meet eachother edge to edge when brought into the same plane with each other, said flaps bein provided one with a notch and the other wit a tongue; said notch and tongue being adapted for interlocking engagement in a manner to revent separation of the flaps from each ot er,

e notch with the margins of the tongue and notch in edge-to-ed e relatlon.

2. A box of sheet material having on oppo;

andthe tongue being adapted to'iit within the notch with the marglns of the tongue and notch in edge-to-edge relation.

with each other, said flaps being 3. A box of sheet material having on opposite side Walls thereof flaps adapted to be folded inwardly and to meet each other edge to edge when brought into the same plane provided one with a notch and the other with a tongue, said tongue being adapted to enter the notch and to lit Within' the same With the margins of the tongue and notch in edge to edge relation, and a flap member of sheet material a plied beneath said a s and to which t elv atter are secured by a hesive material.

4. A box of sheet material having connected side walls' and an end wall, said end Wall embracin flaps on opposite side walls which are folfgied inwardly into the same fglane and meet each other ed e to edge, said aps being provided one Wit a notch and the other with a tongue and the said tongue being adapted to enter said notch and to fit Within the same With the margins of the notch and tongue in edge-.to-edge relation, and other fla s on intermediate side Walls which are fo ded inwardly into the same plane with each other beneath the rst mentioned flaps and to which the latter are secured by adhesive material.

In testimony, that I claim the foregoing as my invention I affix my signaturein the presence of two Witnesses, this 13th day of April A. D. 1907.
